LIGHTNING MTS 225 120v amp draw

[christian]

My 210EXT has a similar inrush amp rating as the MTS 225.

I used to use the 210EXT exclusively on a 240V-30amp breaker, and it did fine, even though it would occasionally throw the breaker on startup, due to the inrush rating at 31 amps.

But then I moved, and the unattached garaged I have at an apartment has a single 120V-20amp breaker where I weld at.

So, for the past 4 years I've been using the 210EXT dual-voltage capacity with no problem to speak of on the 20 amp breaker, up to 120-125 amps for TIG on AC and DC. Although I've popped the breaker a few times when exceeding the duty-cycle by welding at around 125 amps for about 9-out-of 10 minutes. So, I set for no more than 120 amps for applications that I think will take all of that much heat.

I usually unplug the remote garage door opener when using the welder on that sole circuit, too.
